MACHINE FOR SCRAPING OR yDEHAlRlNG ANIMALS.

SPECIFICATION forming part of Letters Patent N o. 720,702, dated February 17, 1903.

Application filed December 13, 1901. Serial No. 851782. (No model.)

To all whom it may concern: u

Be it known that I, JOHN W. KOHLHEPP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Scraping or Dehairing Animals, of which the following is' a full, clear, and exact specification.

My invention relates more particularly to a machine for scraping or dehairing hogs; and it has for its primary object to provide improved and simple means whereby the hair may be scraped from the carcass while passing between suitable Scrapers.

With these ends in view my invention consists in certain features of novelty in the construction, combination7 and arrangement of parts by which the said objects and certain other objects hereinafterV appearing are at-V tained, all'as fully described with reference to the accompanying drawings and more particularly pointed in the claims. Y

In the said drawings, Figure lis a plan section of my improved machine, taken on the line l l, Fig. 2. Fig. 2 is a vertical section thereof, taken on the line 2 2, Fig.'1. Fig. 3 is a detail side elevation of the pulley connections. l

l represents a suitable casing, through the upper part of which passes a track or runway 2, one side of the casing being provided with avertical opening 3 and the other with a pair of outwardly-opening hinged doors 4, which, if desired, may be held normally closed by any suitable spring or device 5, the runway or track 2 passing through the opening 3 and between the said doors 4, and 6 is a gambrel-hook having a suitable trolley running on the track or way 2, which is preferably inclined, as shown in Fig. 2, soA that the carcass may be suspended from the trolley 6 and allowed to run by gravity into the casing l through the opening 3 and pass out through the doors 4, which are automatically opened by the pressure ofthe carcass thereagainst.

Arranged on each side of the track or way l are one or more vertical shafts 7, journaled in suitable beams or bars 8 9 at the upper and lower ends, respectively, and provided'at their upper ends with pulleys l0,connected together by suitable belting ll in such a me mer that all of the arms carried by the shafts 7 will be driven toward the doors 4 during their inner semirevolution. On each of these shafts 7 is secured a drum or hub Y12, having angular vertical ribs or blocks 13, and to vthese vertical ribs or blocks are secured short flexible tangentially arranged strips 14, composed of some suitable material, such as india-rubber, whose outer ends are provided with one or more scraping-blades l5,having their edges turned in the direction of rotation of the shaft. As shown in Fig. 2 of the drawings, there is a multiplicity of these strips'14, se-

' cured one over the other and in close proximity to each other, and each of them is in' turn provided with a multiplicity of the scraping-blades l5, the number shown in the drawings being three. The purpose of the flexible strips 14 is to permit the blades 15 to yield sufficiently when they strikev the carcass as the latter passes between the shafts 7 .on the track l, and thus avoid injuring the flesh, and thetstrips 14 being of slight vertical depth as compared with the depth of the entire series it follows that they will readily conform to the contour of the carcass, and hence enable the blades l5 to reach substantially every portion thereof. The Scrapers thus described are preferably inclosed in the casing l, as before explained, in order to confine the dirt and falling particles; but the principal reason for thus inclosing them is to provide for the employment of one or more spray-pipes 16, arranged at the upper part of the casing and having suitable yspray-apertures on their under sides directed against the carcass as it passes through the casing for the purpose of washing off the loosened hair and other particles. The inlet 3 of the casing may be provided With narrow and wide shields 3a 3b,

which guard in a large measure against the water splashing out.

Having thus described myinvention, what I claim as new therein, and desire to secure by Letters Patent, isl Y l. A machine of the character described comprising a casing, a runway or track passing through the casing, spray-pipes located on opposite sides of the runway or track, vertical shafts located on opposite sides of the runway or track, drums having vertical ribs IOO and secured on the shafts, ilexible strips provided with scraping-blades secured to the vertical ribs and means for rotating the shafts.

2. A machine of the character described comprising a casing provided with a vertical opening at its inner end, narrow and wide shields located at opposite sides of the opening, a runway or track passing through the casing, spray-pipes located on opposite sides of the runway or track, vertical shafts located on opposite sides of the runway or track, drums provided with scraping-blades secured to the shafts, and means for rotating the shafts.

3. A machine of the character described comprising a casin g, spring-doors at the outer end of the casing, a runway or track passing through the casing, spray-pipes located on opposite sides of the runway or track, vertical JOHN W. KOIILHEPP.
